Z型橋梁伸縮縫結構特點與功能

Z型伸縮縫由一條整長的橡膠密封條，一組鋼質邊梁及錨固件組成。鋼質邊梁外側的錨固件，與梁端預埋鋼筋相焊接，澆筑高強度混凝土過渡段后，同梁體連結。Z型伸縮縫具有連結可靠，與橋面接合平順，密封止水、伸縮靈活，行車平穩，使用壽命長的特點。適用于伸縮量為40mm，60mm和80mm的橋梁。

鋼質邊梁：采用16Mn鋼軋制，剖面呈c形。

密封膠條：采用氯丁或三元乙丙橡膠制造，具有良好的耐老化、耐曲撓性能。

錨固件：有錨釘、錨環、錨板結構三種，橋梁工程師可根據橋面板設計厚度選用，本公司也可特殊設計制造。

關于Z型橋梁伸縮縫產品在橋梁上安裝時的步驟及注意事項：

1、當工程施工單位在安裝橋梁伸縮縫時，一旦發生碰撞變形，很難修復為合格產品，所以在安裝的全過程中，一定要采取措施保護，嚴禁任何車輛通過。

2、一定要精心操作。如果出現現場不易調整，所以對伸縮縫的成品檢查一定要認真、仔細。不合格不可運至現場。

3、在橋梁伸縮縫在安裝前，要與設計圖和現場核對位置、尺寸無誤后，再穩放入預留槽。要將橋上各接縫處縫隙一定要用聚苯乙烯泡沫板塞嚴，防止澆注保護帶混凝土時灌入，使縫失效。同時，也不可將裝置內灌進混凝土，以免更換V形象膠帶時受阻。

4.、在保護帶混凝土澆筑后，前7-8日一定要及時灑水養護，以利強度增長和防止裂縫出現。

GQF-Z 型伸縮縫公路橋梁專用的伸縮裝置，它由一組鋼質邊梁及錨固件組成加一條整長的橡膠密封條組成。在伸縮裝置的鋼質邊梁外側的錨固件，與梁端預埋鋼筋相焊接，澆筑高強度混凝土過渡段后，同梁體連結。 GQF-D型伸縮縫具有連結可靠，與橋面接合平順，密封止水、伸縮靈活，行車平穩，使用壽命長的特點。適用于伸縮量為 40mm ， 60mm 和 80mm 的橋梁。

A telescopic device for GQF-Z expansion joint highway bridge is composed of a group of steel side beams and anchors, plus a whole length of rubber sealing strip. The anchor on the outer side of the steel edge beam of the expansion device is welded with the embedded steel bar at the end of the beam, and then the high strength concrete transition section is poured and connected with the beam body. The GQF-D type expansion joint has the characteristics of reliable connection, smooth connection with the bridge deck, sealing and sealing, flexible expansion, stable running and long service life. Bridge suitable for 40mm, 60mm and 80mm expansion.
GQF-Z 型伸縮縫是國內交公路規劃設計院設計的一種新穎橋梁伸縮裝置，產品適用于大流量交通地段的公路、城市橋梁、高架道路與立交工程。
GQF-Z type expansion joint is a new type of bridge expansion device designed by domestic highway planning and Design Institute. The product is suitable for highway, urban bridge, elevated road and interchange project with large traffic volume.
GQF-Z 型伸縮縫主要材料：鋼質邊梁：采用 16Mn 鋼軋制，剖面呈c形。密封膠條：采用氯丁或三元乙丙橡膠制造，具有良好的耐老化、耐曲撓性能。錨固件：有錨釘、錨環、錨板結構三種，公路橋梁工程師可根據橋面板設計厚度選用。大家可以參考：C型橋梁伸縮縫的分類及產品適用范圍中的詳細介紹
GQF-Z type expansion joint main material: steel side beam: rolled by 16Mn steel, the section is C shape. Sealing strip: made of neoprene or three yuan ethylene propylene rubber, has good aging resistance, bending resistance performance. Anchor: there are three kinds of anchor, anchor ring, anchor plate structure, highway bridge engineer can choose according to the thickness of bridge deck design. We can refer to: C bridge expansion joint classification and product range of application in detail
GQF-Z 型伸縮縫是適用于設計荷載為汽超 20 掛超120 級的直橋、彎橋、斜橋、坡橋等公路和城市橋梁。 由于它采用鋼質邊梁、鳥形橡膠密封條和錨固構件組成。在橋梁梁體因溫差等因素引起位移時，機械固定在邊梁溝槽中的橡膠密封條能自由折迭伸縮。起到防水防塵作用。行駛車輛的沖擊力，通過邊梁和焊接的錨固構件傳遞到橋梁結構中。該型伸縮縫適用于伸縮量 0～80mm 的橋梁。
GQF-Z type expansion joint is applicable to the design of steam load for the super 20 super 120 hang straight bridge, the curved bridge, skew bridge and ramp bridge, highway and city bridge. Because it is made of steel side beam, bird shaped rubber sealing strip and anchor component. In the bridge body due to the temperature difference caused by mechanical displacement, fixed to the side beam groove in rubber seal can free telescopic folding. Play the role of waterproof and dustproof. The impact force of the moving vehicle is transferred to the bridge structure through the side beam and the welded anchorage member. This type of expansion joint is suitable for bridges with 0 ~ 80mm expansion capacity.
1、GQF-Z 型橋梁伸縮縫整條采用氯丁或三元乙丙橡膠制作，具有良好的耐老化、耐曲撓性能。適應橋梁梁端 水平、橫向、豎向變形，伸縮阻力極小。
1, GQF-Z type bridge expansion joint is made of neoprene or three yuan ethylene propylene rubber, and has good aging resistance, bending resistance performance. Adapting to the horizontal, horizontal and vertical deformation of the bridge beam end, the minimum expansion resistance is very small.
2、鋼質邊梁采用 16Mn 精軋而成，錨固板及Φ16錨固筋具有良好的機械性能。作用于邊梁上的車輛沖擊力，通過錨固構件均衡的傳遞到梁體上，有很長的使用壽命
2. The steel side beam is finished by 16Mn finishing, and the anchoring plate and the 16 anchor bar have good mechanical properties. The vehicle impact force acting on the side beam is balanced to the beam body by the anchor component and has a long service life
